Ok here it goes I was needing a live wire for light that I snipped couple years back so when I found wire again there was no power so pulled out all the fuses because it's a nightmare to get into so checked all fuses they were ok so put it back together but now when u start up the lights come on and the key fob doesn't work and the clock keeps resetting so got aa out and they said its a bad earth it's dropping 1o/ov how do I fix this
